    Part 2 Basics of the LPX-250 2. Suitable and Unsuitable Objects for Scanning The LPX-250 cannot scan every single kind of object.

  • Page 20: Plane Scanning

    2. Suitable and Unsuitable Objects for Scanning 3. Plane Scanning 3. Plane Scanning Features of Plane Scanning This mode uses parallel laser beams to scan while rotating the table and laser head in synchronization. Because this mode can obtain comparatively stable scanning results regardless of the shape of the object, you can use it as an all-purpose mode. You can use it to scan up to six surfaces at one time (multi-plane composition).

  • Page 21: Rotary Scanning

    Part 2 Basics of the LPX-250 In general, increasing the number of scanning surfaces results in greater scanning precision with correspondingly fewer conspicuous seams. In the example of the doll, however, only one of the five scanning surfaces can capture the voids. From the standpoint of capturing voids, two surfaces are more effective.

    2. Detailed Settings for Rotary Scanning 3. Finishing Detailed Areas Using Rescanning 3. Finishing Detailed Areas Using Rescanning After you have scanned an entire object, this feature rescans just one portion with changed conditions. Basic scanning should always be performed using the best possible conditions, of course, but by using rescan to finish detailed portions you can make the data even more highly finished.
  • Page 33 Part 4 Features for Better Scanning 4. Hold down the SPACE key and drag to position the area you want to rescan at the front. This makes the front surface the direction of laser-beam emission. As you determine the orientation, try to angle it so that the laser light can penetrate sufficiently (or so that the laser light passes through).

    3. Finishing Detailed Areas Using Rescanning Scanning a Specific Area in Greater Detail You perform coarse scanning of the entire object using rotary scanning, then rescan just the required areas at a finer pitch. This can reduce the size of the data and also shorten the scanning times. This feature is for rescanning a portion in the rotary-scanning mode. 1.

  • Page 36 4. Case Studies for Better Scanning This example involves using the two scanning modes to scan an object that has a nearly cylindrical shape. You can use either mode for scanning, but rotary scanning achieves the shortest scanning times. The scanning pitch is equivalent for both, but rotary scanning produces smoother surfaces.

  • Page 37: The Scanning-Start Direction For Plane Scanning

    Part 4 Features for Better Scanning The Scanning-start Direction for Plane Scanning This is an example where the scanning-start direction is changed with plane scanning. It is a good idea to give thought to the direction in which cavities and voids can be most easily captured (that is, the direction in which the laser beam passes), and also to keep in mind what area of the object is most important.

  • Page 38: Object Mounting Location For Rotary Scanning

    4. Case Studies for Better Scanning Object Mounting Location for Rotary Scanning In rotary scanning, the laser light is beamed toward the center of the table. This means that when the object is uneven, the penetration of the laser light varies greatly according to the object's mounting location. This case takes this point into account and deliberately shifts the mounted position away from the center.
